Purdue ZTAs have a huge Big Man On Campus philanthropy. They have week long fundraising with penny wars, date auctions, restaurants on campus donating, tshirt sales, and the list goes one! Then at the end of the week the guys compete in a talent and question pageant. It is so much fun and a really well done production. Last year they raised several thousand dollars for breast cancer awareness, it was awesome. If you want to know more, I would check out their website or try to contact one of them
